/* =====================================================================
   style.css — ธีม Aurora UI
   สเปกต้นฉบับ: https://designmd.app/library/aurora-ui (DESIGN.md)

   - พื้นหลังไล่สีแบบแสงเหนือ 3 สี: ฟ้า #0080FF · บานเย็น #FF1493 · ฟ้าอมเขียว #00FFFF
     เคลื่อนช้า ๆ รอบละ 9–12 วินาที และขยับด้วย transform เท่านั้น (ลื่น ไม่กินแบต)
   - ฟอนต์ระบบ (system UI) ตามสเปก + Anuphan สำหรับตัวอักษรไทย
     (ฟอนต์ระบบบน Windows ไม่มีตัวไทย ถ้าไม่กำหนดเอง แต่ละเครื่องจะหน้าตาไม่เหมือนกัน)
   - มุมโค้ง 0.75rem · เงาบาง 0 2px 12px · ขอบ 1px
   - ที่ปรับจากสเปก: ปุ่มใช้ฟ้า #0070E0 แทน #0080FF เพราะตัวอักษรขาวบน #0080FF
     ได้ contrast แค่ 3.8:1 ไม่ผ่าน WCAG AA (สเปกเองก็กำหนดให้ตรวจ contrast)
   - ยังเก็บกรอบ detection รอบชื่อ และจอกล้องวงจรปิดไว้ เพราะเล่าเรื่องผลงานจริง
